add some fun randomly generated effects or abilities to it, like:
20% of the time there's 50% gravity, u can jump twice as high and float slowly down
20% of the time the floor ices where you slide a lot effecting your momentum
10% of the time it's 25% gas with a random combo of one other effect (accompany this with a planet wide announcement 2 minutes before it happens)
30% of the time things are normal
20% of the time the club becomes 90% translucent giving the feeling of partying in space, but you can still see enough of it to navigate.
and call it The Entropy Lounge
